The subtropical storm had an unusual origin by forming from an interaction of two different systems near the Yucatán Peninsula.

This occurrence is unusual, but not unique, as Subtropical Storm One in the 1974 season formed in similar pattern.

[1] A reconnaissance flight on June 17 reported that there appeared to be multiple transient circulations at the surface, but no well-defined center.

[2] A circulation began to form on June 18 in the eastern Gulf of Mexico, prompting gale warnings.

The depression made landfall on the morning of June 18 just north of Spring Hill, Florida and gained subtropical storm status over land.

The subtropical storm moved to the northeast and crossed the Outer Banks of North Carolina on June 19.

The same day, a gale warning was issued from Cape Henlopen, Delaware to Watch Hill, Rhode Island.

[8] Most of the storm's effects were felt in Florida where it made landfall on the morning of June 18, causing gales, heavy rains, flooding, beach erosion and tornadoes.

[10][11] High tides and waves caused flooding and beach erosion from Naples to the Tampa Bay area.

Several bulkheads and rock revetments experienced minor damage in Naples and Marco Island.

Several man‑made dune structures seaward of the Coastal Construction Control Line in Collier County received minor damage at Vanderbilt Beach and Marco Island.
